GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 771,321, dated October4, 1904.

Application filed November 18, 1903. Serial No. 181,672. (No model.) i

To all whom it may concern:

Be it known that I, HERMAN Gr. PAPE, acitizen of the United States,residing at New York, in the county of New York and State of New York,have invented a new and useful Gas- Stove, of which the following is aspecification.

The invention relates to improvements in gas-stoves. r

The object of the present invention is to improve the construction ofgas-stoves and to provide a simple, inexpensive, and efficient one whichWill be strong and durable and which will be economical in theconsumption of gas.

A further object of the invention is to provide a stove of thischaracter which will afiord a maximum amount of heat for a givenquantity of gas and which will be adapted for both lighting and heatingpurposes.

Another object of the invention is to provide a gas-stove designedparticularly for heating apartments or rooms and capable of producing arapid circulation in a room and of quickly heating the same.

With these and other objects in view the invention consists in theconstruction and novel combination and arrangement of parts, hereinafterfully described, illustrated in the accompanying drawings, and pointedout in the claims hereto appended, it being understood that variouschanges in the form, proportion, size, and minor details of constructionwithin the scope of the claims may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a vertical sectional view of a gas-stoveconstructed inaccordance with this invention. Fig. 2 is a horizontalsectional view taken substantially.

on the line 2 2 of Fig. 1 and illustrating the construction of one ofthe conical shells or hoods. Fig. 3 is a similar view takensubstantially on the line 3 3 of Fig. 1 and illustrating theconstruction of the burner and the stand.

Like numerals of reference designate corresponding parts in all thefigures of the drawlngs.

l designates a base or stand consisting of legs 2, centrally connectedand formed intewill be readily understood.

gral with one another, the stand or base being preferably a singlecasting; but any other form of stand or base may be employed, as Thecenter of the stand is pierced by the lower end of a vertical rod 3,having a lower threaded end receiving a nut 4, which engages a washer 5,that is interposed between the nut and the lower face of the center ofthe stand or base.

' The rod may be of any desired length, and its upper end 6 is threadedand fits in a socket 7 of an urn 8, constructed of metal and preferablyprovided with a porcelain receptacle 9, which is also in the form of anurn and which is adapted to holda quantity of WQI'BIX' The vertical rodor standard forms a support for a series of approximately frusto-conicalshells 10, constructed of sheet metal, cast-iron, or any other suitablematerial, and supported by tubular sections 11, which are disposed onthe vertical rod or standard, as clearly illustrated in Fig. 1 of thedrawings. The lowermost tubular section is adapted to receive andsupport a burner 12, and the second tubular section is placed on the rodor standard after the bottom tubular section and the burner have beenarranged thereon. The lowermost shell is then placed on the rod orstandard, and the other tubular sections and shells are successivelyarranged on the same. The rod may be of any desired length, and anynumber of shells may be employed to provide a gas-stove of the desiredheating capacity. Each tapering shell or hood is provided with ascalloped lower edge, and it has a horizontal top portion 13, providedwith a'cluster of fine perforations forming vents or passages for theescape of the heated air. The inclined body portions of the shells orhoods are imperfo-- rate and are exposed, as shown, no surroundingcasing being employed and the heater being adapted to suck or draw inthe surrounding air, whereby the same is rapidly heated. The stove inthis manner is adapted to cause the circulation of air in a room orapartment, the circulation being substantially as indicated by thearrows in Fig. 1 of the drawings. The surrounding air is drawn inwardbelow the hoods or shells and is heated, a portion ofthe heated airpassing directly up ward through the apertures of the top horizontalportions of the said shells or hoods and the greater portion of the airpassing downward around the lower edges of the hoods or shells, asindicated by the said arrows. In this manner a large volume of air israpidly heated, and as the air comes directly in contact with the heatedsurfaces of the shells or hoods the heating of a room is effected at theexpenditure of a minimum amount of fuel.

The burner 12 is of the Bunsen type, and it consists of an annular tubeor body portion and a connecting web or spider 14:, which is providedwith a central perforation for the rod or standard. The annular body orcasing is provided at the top with a series of projecting nipples 15 forthe reception of asbestos mantles 16, forming burners, as clearlyillustrated in Fig. 1 of the drawings. A gas-pipe 17 is connected withthe body portion or casing of the burner, at one side thereof, forsupplying gas, and the said body portion or casing is provided at itsbottom with a series of apertures 18, adapted to admit air into thecasing, the air and gas mixing in the usual manner. Instead of employingasbestos in the construction of the mantles any other suitable similarmaterial may be used, as will be readily understood. The gas-pipe 17 maybe constructed of flexible material and provided with means for enablingit to be connected with a burner or other suitable source of supply,whereby the stove may be connected with the gas-supply of a house orbuilding without necessitating any alteration in the construction of theusual supply-pipes and burners. The asbestos mantles of the burnerbecome highly heated and are adapted to afford light, and any desirednumber of mantles may be provided to secure the desired lighting power.

The nut and the threaded socket of the metallic urn or receptaclesupport 8 detachably secure the parts of the heater together and enablethe same to be rigidly clamped in the position illustrated in Fig. 1 ofthe drawings.

It will be seen that the device, which is exceedingly simple andinexpensive in construction, possesses great strength and durability,that it is adapted for both lighting and heating, and that it is capableof securing a maximum amount of heat from a given amount of fuel.Furthermore, it will be clear that as the tapering shells or hoods areopen or exposed the heater is adapted to rapidly suck in the surroundingair, and that it is capable of creating a circulation in a room orapartment and of quickly heating the same.

After the burner is lighted the air and gas, which are mixed, are heatedbefore they are consumed. The lower conical shell keeps the burnercompletely surrounded by intensely hot air and heats the gas as it flowsinto the pipe or body of the burner and expands the gas before the sameis consumed, thereby lessening the consumption of gas. The stove 1consumes less gas than those stoves in which the gas is not heatedbefore it is consumed, and more intense heat is obtained by heating theair and gas previous to combustion.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. A combined lighting and heating stove, comprising a vertical seriesof approximately frusto-conical shells spaced apart, and each having acluster of fine perforations at the top portion for the passage of theproducts of combustion, said shells being also provided at the topportion with openings, a burner lo cated beneath the series of shells, astandard passing through the openings and closing the same to thepassage of the products of combustion, whereby the same are caused topass both through the said perforations and around the lower edges ofthe shells, and means for maintaining the shells in their spacedrelation, substantially as described.

2. A combined lighting and heating stove, comprising a standard, avertical series of approximately frusto-conical hoods or shells piercedby the standard and exteriorly arranged, a series of spacing-tubesdisposed on the standard and supporting the hoods or shells,and aburner, substantially as described.
